Themechanisms for driving all these drums and controlling the positions ofthe train drum and the track drum are contained in a frame 7 which islocated between and `partly within' these last 'two iis drums.,A Theframe carries a driving mechanism and two ,positioning mechanisms onefor the. traclrdrum and one for the train drum. Thci driving mechanism,4Figs. `2 and 6, comprises a motor, 8a, 8" or 8", driving through awgeartrain 9, 10, 11, 12, 13,l 14 a diiierentialconsisting of planet bevels15 f 15 a bevel 16 connected to the track drum .stead Yof tivo and nodriving mechanism, as

the driving mechanism in the other frame also operates these positioningmechanisms through the axial shaft of the drums which runs through bothframes. The 'mechanism for the hoiir drinn is identical with that forthe train drum and illustration in plan is not repeated. It is clampedon the huh of ing position. The pawl is drawn into en-' gaging positionby a magnet 23a, 23"` or 2. for stopping the mechanism at an indicatinglposition; A contact cylinder. 24 consisting of a brass sleeve with agroup ofV twelve spirally disposed projecting contact pins mounted on aninsulating core is revolved hy a gear 25 of the same size as the gearwhich carries the drum and being in mesh with thc same pinion revolveswith it so as to bring a. contact Vpin under one of the group of twelveVcontact fingers 26 26 at each indicating position. `An additionalfin"-l ger 27, continually in contact with thesleeve,

is connected with the magnet. The train drum, Fig. 5, is clamped at oneend to the huh of a gear 2S which is frictionally driven from theshait.y A collar 29 clamped to the shaft has i diametrical groove on oneside y in which lies a spring wire 30 the. ends of ist wat

which bear in a groove turned in the inner side ofthe i'iiii of thetrain-drum gear 28. The

balance of the mechanism is of the same character as the mechanism forcontrolling the track drum and consists of a pinion 31,

a gear 40 which is'rictionally driven from the shaft through a collar 41clamped to the shaft and driving through a spring wire 42, The balanceof the mechanism, shown only in Fig. V8, includes' a pinion 43, ratchet44, paw1'45, magnet 46, contact cylinder 47, gear 48, group of twelvecontact fingers 49 49 and additional finger 50.

Each of the wires of the g'roup'from the positioncontacts' leads to one of six sets of contact segments 111 111 therebeing three in each set joined .by a ring segment.

At sixty of their corners provision is made L for connecting a segmentby a plug 112 with one of eighteen alternating segments 11B 113 whichare joined Vby a ring'and connected through the wire 105 with the otherside of the source of current.

For the unit-minute indicating mechanism from `the group of positioncontacts to the operating board is a groupof ten wires 114 11i. F roi'nthe magnet coils are wires 115", 115", 115, to normally openindicatorselecting contacts 110, 116", 116, also closed by the pushbuttons with a wire n 117 through a signal lamp 1193 to one side of thesource of current.v Eachof the wires of the group from the positioncontacts leads to one of a group of buttons 119 1 19 inten sets therebeing six in each set interconnected by wires 120 120. Tliebuttons areplaced opposite the junctions of the tenniiniite indicator positioning`segments with the altcrnatingsegments so that the `setting ofthe plugfor connecting the segments also connects a button with the other sideof the'soiirce of current.

All of th'e 'contacts on the push buttons in the positioningcircuits ot'the several indicating mechanisms are` as rdescribed in connection'iiiththe circuits of the trackindicating 'nicclianisnn so placed'tliat theywill 'not open until the buttons fully return and hold tlie positioningmagnets until the inotorsliave time to stop. The time-posi` tioningcontacts at the operating board are used for -all the indicating unitsbut as the` circuits are all normally open at the push buttons the `timeindication will b e transferred only to the indicator unit which isselected for operation by pressing its push button. The operation ofsetting an indi-` catoriinit consists in first placing all the l" plugsat the desired indications and then pressing the; biitto'which selectsthe unit on which the indications are to appear and holding down thebutton until the five signal lamps light to show that all the indi- Ieating mechanisms alte properly set. i

In the application ofthe invention illustrated `for announcingarrivingtrains aclassiicationof the trains `will be ymade. and' eachunit will be used for the announcement of a series of trains which givesimilar=1- service, as such trains are widely separated in then-arrivingtime and -least likely to require concurrent announcement. Aseachtrainarrives and discharges its passengers the indicator on which it isshown willQbe set for the'next train in the classpgi'ving the expectedtime of arri-valaccordini; to the information at hand, and tlietinie may4 be revised and reset when necessary.; `Under the` usual conditionsbfoperation thetraclrso is not assigned until the train reaches the'yardfso that Jthe track drum will first be used to give notice as towhether or not the train is reported on time and the trackindicatingmechanism will be reset when the train reaches the yard. As in theinterval the plugs will have been shifted for setting other units, andto avoid the necessity of restoring these plugs to the time of the trainthese groups will be at once loclrcd:against` movement.

In order to give warning of the approach 105` of the train a lightingswitch consisting of a coinmutator '122 is revolved bytlietrackindicating mechanism through the gear 123 and is arranged toclose the circuit betweentwo brushes A124: 124 in the circut withthe110`` lamps 125 125 when this mechanism is set to show the track, sothat the Vunit will have extra lighting and attention will beattractedto it. y

The frames containing the operating mechanism for each unit aresupported on brackets 1213 126 which lie between the ends of the"druin.The brackets also carry the front platethrough which the indication isread.` A Allq the mechanical parts forming an indicating unit arethereby bound together and eacli unit is `supported like a, drawer in acabinet 127. i The connecting wires to each are looped soithat any unitcan be drawn `out of the cabinet for inspection without '12,5
